Answer:the number is 25

Step-by-step explanation:

2a-7=43

Collect like terms

2a=43+7

2a=50

Divide both sides by 2

2a/2=50/2

a=25

Answer:

Option B k > 0

Step-by-step explanation:

we know that

Observing the graph

The slope of the line is positive

The y-intercept is negative

we have

$3y-2x=k(5x-4)+6\\ \\3y=5kx-4k+6+2x\\ \\3y=[5k+2]x+(6-4k)\\ \\y=\frac{1}{3}[5k+2]x+(2-\frac{4}{3}k)$

The slope of the line is equal to

$m=\frac{1}{3}[5k+2]$

Remember that the slope must be positive

$5k+2> 0\\ \\k > -\frac{2}{5}$

The value of k is greater than -2/5

Analyze the y-intercept

$(2-\frac{4}{3}k) < 0\\ \\ 2 < \frac{4}{3}k\\ \\1.5 < k\\ \\k > 1.5$

1.5 is greater than zero

the solution for k is the interval ------> (1.5,∞)

therefore

must be true

k > 0

I need help with this practice problem solving This is trigonometry from my ACT prep guide

Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

$f(x)=A\cos (\frac{2\pi}{T}x)+b$

In the given case, you have:

A = 4

T = 3π/4

b = -3

By replacing you obtain:

$\begin{gathered} f(x)=4\cos (\frac{2\pi}{\frac{3\pi}{4}}x)-3 \\ f(x)=4\cos (\frac{8}{3}x)-3 \end{gathered}$

Hence, the answer is:

f(x) = 4cos(8/3 x) - 3
